网络端口聚合绑定

mode=0 (balance-rr) mode=1 (active-backup) mode=2 (balance-xor) mode=3 (broadcast) mode=4 (802.3ad) lacp mode=5 (balance-tlb) mode=6 (balance-alb)

一、bind 配置

1、netplan 网卡 bind 配置

cat /etc/netplan/00-installer-config.yaml
network:
  ethernets:
    enp65s0f0:
      addresses: []
    enp65s0f1:
      addresses: []
  bonds:
    eth0:
      addresses: [192.168.0.61/24]
      gateway4: 192.168.0.1
      nameservers:
        addresses: [114.114.114.114]
      interfaces:
        - enp65s0f0
        - enp65s0f1
      parameters:
        mode: 802.3ad
        mii-monitor-interval: 100
        lacp-rate: fast
        transmit-hash-policy: layer3+4

2、交换机配置

sys
display current-configuration

interface GigabitEthernet 0/0/3
undo port link-type
undo port default vlan

nterface GigabitEthernet 0/0/4
undo port link-type
undo port default vlan

interface Eth-Trunk 1
mode lacp
port link-type access
port default vlan 20
max active-linknumber 2

interface GigabitEthernet 0/0/3
eth-trunk 1
lacp priority 100

nterface GigabitEthernet 0/0/4
eth-trunk 1
lacp priority 100

display trunkmembership eth-trunk 1
display eth-trunk 1

3、查看 bond 网卡

cat /proc/net/bonding/eth0

三、其他

1、centos网卡绑定

/etc/sysconfig/network-scripts/ifcfg-eth0

TYPE=Ethernet
BOOTPROTO=none
NAME=eth0
DEVICE=eth0
ONBOOT=yes
MASTER=bond0
SLAVE=yes

/etc/sysconfig/network-scripts/ifcfg-eth1

TYPE=Ethernet
BOOTPROTO=none
NAME=eth1
DEVICE=eth1
ONBOOT=yes
MASTER=bond0
SLAVE=yes

/etc/sysconfig/network-scripts/ifcfg-bond0
TYPE=Bond
BOOTPROTO=none
NAME=bond0
DEVICE=bond0
ONBOOT=yes
BONDING_MASTER=yes
BONDING_OPTS="mode=1 miimon=100"
IPADDR=10.10.10.12
NETMASK=255.255.255.0
GATEWAY=10.10.10.1
DNS1=114.114.114.114

systemctl restart network

其他方式

配置 bond0 绑定模式
创建 /etc/modprobe.d/bonding.conf，加入以下内容
alias bond0 bonding
options bond0 miimon=100 mode=1

载入 bonding 模块，重启 network 服务
modprob bonding
systemctl restart network

2、ubuntu网卡绑定

network:
  ethernets:
    enp1s0:
      addresses: []
    enp6s0:
      addresses: []
  bonds:
    eth0:
      addresses: [192.168.0.127/24]
      gateway4: 192.168.0.1
      nameservers:
        addresses: [114.114.114.114]
      interfaces:
        - enp1s0
        - enp6s0

apt-get install ifenslave

vim /etc/module
